Abstract
The problem of packing space with regular tetrahedra has a 2000 year history. In this talk, the speaker will survey the history of the problem. It includes work by mathematicians, physicists, chemists, and materials scientists. Much progress has been made on it in recent years, yet there remain many unsolved problems.
